I use two Android devices regularly. A Nexus 5 which is my daily driver, calendars, Google Keep, etc. The second device is an Asus Tablet which I use to consume - newspapers, news, magazines, internet, etc. I try to minimize all the alerts on this tablet since I don't need any notifications from my calendar or other daily apps.
I am a heavy user of Google Keep on my Nexus 5 but have not installed it on my tablet (on purpose). And yet, each time I set a reminder that I want to see on my phone, I also get a notification on my Tablet of the form (e.g.) "Pick Up Eggs - Install Google Keep". It also uses the Google Now reminder icon (finger with a bowtie) and not the Google Keep icon (lightbulb). I should also mention that I do not have Google Now enabled on any of my devices.
I do not want Google Keep nor the reminders on my Tablet. I've tried removing various sync services under the Google Account but can't seem to find the one that is synchronizing the Google Keep reminders to my Tablet.
Any suggestions as to how to get rid of these useless notifications?
